They aren’t, which makes this meme even funnier because in my experience Canadians and Aussies are pretty likely to understand both systems and wouldn’t have a problem identifying either.
I’d put money on this having been made by a European.
As a Canadian myself, it really depends. Most of us only understand farenheit in certain contexts. Some of us can understand it for weather but I think that’s mostly older generations. I use farenheit for oven and pool temperature only. In every other context, it is meaningless to me.
The crossover is so fascinating to me.
Like you just nonchalantly use it for pools and ovens and nothing else. Kind of like we use liters randomly for certain soda bottles and basically nothing else.
Oh I know! It’s so weird. Ovens are probably because we get ours from the US, but why we do pool temperature in farenheit is a mystery to me.
